Washington, Ramadan 15, 1436, Jul 2, 2015, SPA -- Metropolitan police closed an investigation into apparently false reports of a shooting Thursday at the Washington Navy Yard that tied up traffic in the US capital, dpa reported. Amid heightened security awareness ahead of Saturday's Independence Day celebrations, traffic was snarled around the city as police blocked streets and tourists were evacuated from Lafayette Park across from the White House and from the Smithsonian museum complex. -- SPA 23:25 LOCAL TIME 20:25 GMT www.spa.gov.sa/w
